To be certain, you should:
* Consult your vehicle's repair manual: This will provide diagrams and precise locations.
* Use a reliable online parts diagram: Many auto parts websites allow you to search by year, make, and model, then view detailed diagrams showing sensor locations. Search for "2001 Oldsmobile Aurora parts diagram" on your preferred parts site.
Without visual confirmation using one of these methods, giving a precise location is difficult and potentially misleading. Always refer to a reputable diagram before attempting any repairs.
